Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an electric lock control device that controls an electric entrance lock from an information board that controls and monitors other electric devices.

[Background Art] Conventionally, in this type of electric lock control device in which an electric door lock is controlled from an information board that controls and monitors other electric devices, it is difficult to lock, unlock, and monitor the opening/closing status of the electric lock. The main body of the control device, which controls the locking and unlocking of the electric lock, and the operation display section, which consists of an electric lock operation switch for controlling the locking and unlocking of the electric lock, and an operation display section that displays the open/close status of the electric lock, are both located in the information panel. However, there were problems in that the information panel became significantly larger, making it difficult to secure an appropriate installation space, and that the information panel was too conspicuous and could spoil the aesthetics of the room.

[Purpose of the invention] This invention was made in view of the above points, and its purpose is to prevent the information board from becoming significantly larger and to easily secure the space for installing the information board. To provide an electric lock control device which can be used to control a lock and which does not spoil the beauty of a room due to an information board.

[Disclosure of the invention] (Example) Figures 1 to 4 show an example of the invention, in which an electric door lock 1 is used to control and monitor other electrical equipment (intercom device, crime prevention, disaster prevention equipment, etc.). In the electric lock control device similar to the conventional example, which is controlled from the information panel 2 that performs the locking of the electric lock 1,
An operation display consisting of a control device main body 3 that monitors the unlocking and opening/closing states, an electric lock operating switch 4 for controlling the locking and unlocking of the electric lock 1, and an operation display section 5 that displays the opening/closing status of the electric lock 1. The control unit 6 is formed separately, the operation display unit 6 is disposed on the information panel 2, and the control device main body 3 is housed in a free space 7a of a power distribution device such as a distribution board 7. be. Here, in the embodiment, the electric lock operation switch 4 is formed by one pressed lead switch, and the information board 2 operation display part 6 is a light emitting diode that lights up when the electric lock 1 is unlocked. It is formed in The control device main body 3 is composed of an electric lock circuit 3a shown in FIG. 2 and _a security circuit _3b shown in FIG. Formed by circuit CR, D-flip-flop circuit FF ₁ , unlocking control relay RY ₁ , locking control relay RY ₂ , drive transistors Q ₁ , Q ₂ , step-down transformer T, rectifier diode bridge DB, and constant voltage circuit VR The relays RY _{1 and} RY ₂ are operated alternately each time the electric lock operation switch 4, which is a push-in lead switch, is pressed, and the electric lock 1 is locked and unlocked via the relay contacts r ₁ and r ₂ . The door is unlocked and locked by passing pulse currents of different polarities through the coil L. In addition, the security circuit 3b
Transistor Q ₃ ~ Q ₉ and security output relay
RY _{3 ,} and the operation display unit ₅ and The crime prevention output relay RY ₃ is controlled, and the light emitting diode of the operation display section 5 is turned off only when the entrance door is closed in the locked state, and the light emitting diode of the operation display section 5 is turned off, and the light emitting diode of the operation display section 5 is turned off only when the electric lock 1 is in the locked state and the entrance door is opened. When the security output relay RY ₃ is driven, its relay contact r ₃ is turned on and the security output is sent to the information panel 2. Note that the circuit power supply (DC12V) is obtained from the power supply circuit (constant voltage circuit VR output) of the electric lock circuit 3a.
FIG. 4 shows an example in which the control device main body 3 is arranged in a distribution board 7 having a free space 7a, and a base 1 is mounted on a wiring rail to which a plurality of breakers 9 are attached.
The control device main body 3 is disposed through the power distribution board base 8, and the power distribution board top cover 10 is covered with the power distribution board base 8.
A cover 12 is attached to the opening formed in the opening.

The operation of the embodiment will be specifically explained below. Now, by pressing the electric lock operation switch 4 consisting of a push lead switch, the output of the buffer formed by the AND circuit _A1 becomes "H" level.
At the rise of the buffer output, the D-flip-flop circuit output (Q,) is inverted, and the pulse generation circuit formed by the time constant circuit CR and the AND circuit _A2 generates a buffer for T seconds after the rise of the buffer output. A pulse signal at "H" level is output. The AND circuits A ₃ and A ₄ combine the above pulse signal with the D-flip-flop circuit FF ₁ (Q,
The AND circuit with Q) is calculated, and the AND circuit is
Either of the A ₃ and A ₄ outputs is at the "H" level for T seconds, and one of the transistors Q ₁ and Q ₂ is turned on, and the electric lock control relay RY ₁ or RY ₂ is energized. When relay contact r ₁ or r ₂ of either electric lock control relay RY ₁ or RY ₂ is turned on, unlocking excitation current flows in the driving coil L of electric lock 1 in opposite directions.
The electric lock ₁ is unlocked or locked by flowing an excitation current I ₁ or an unlocking excitation current I 2 . For example, when the electric lock operation switch 4 is turned on, D
- When flip-flop circuit FF ₁ output Q goes to “H” level, AND circuit A ₃ output goes “H” for T seconds
level, transistor Q ₁ is turned on, electric lock control relay RY ₁ is energized, relay contact r ₁ is turned on, unlocking excitation current I ₁ flows to drive coil L, and electric lock 1 is unlocked. It's becoming like that. Next, when the electric lock operation switch 4 is turned on again, the output of the D-flip-flop circuit _FF1 goes to the "H" level, so the output of the AND circuit _A14 goes to the "H" level for T seconds, and the transistor _Q2 turns on. When turned on, electric lock control relay RY ₂ is energized, relay contact r ₂ is turned on, locking excitation current I ₂ flows to drive coil L, and electric lock 1 is locked. On the other hand, in the security circuit 3b, transistors Q ₈ and Q ₉ are controlled by a lock/unlock detection switch S ₁ that is turned on when the electric lock 1 is locked and turned off when it is unlocked. Open/close detection switch _S2 that turns on when the is closed and turns off when it is opened
Transistor _Q3 is controlled by . Here,
When the electric lock 1 is in the locked state with the lock/unlock detection switch S ₁ turned on, the transistor Q ₈ will be turned off, and if the transistor Q ₇ is turned off at this time (that is, the front door is closed). (If the electric lock 1 is locked, the transistor _Q6 is turned off, and the light emitting diode of the operation display section 5 is turned off, indicating that the electric lock 1 is locked and the entrance door is closed.) On the other hand, when the door is unlocked or the front door is opened, either transistor Q ₇ or Q ₈ is turned on, transistor Q ₆ is turned on, and the light emitting diode of the operation display section 5 is turned on. It's starting to light up.

Also, if the entrance door is opened and the open/close detection switch _S2 is turned off even though the electric lock 1 is in the locked state. Transistors Q ₃ and Q ₄ are turned off, lock/unlock detection switch S ₁ is turned on, and transistor Q ₃ is off, so transistor Q ₅ is turned on and security output relay RY ₃ is energized. Relay contact _r3 is turned on and a crime prevention output is input to the information board 2, and an alarm means (not shown) is driven by this crime prevention output.

The control device main body 3 configured as described above includes a power supply circuit, a control monitoring circuit, etc. formed using relatively large components, and is a relatively large circuit block. In the end, this large circuit block will be placed in the free space 7 inside the distribution board 7.
Since the information panel 2 houses a small operation display section 6, the information panel 2 does not become large in size, and the space for installing the information panel 2 can be easily secured. Moreover, the information panel 2 prevents the interior aesthetics from being spoiled. In addition, in the embodiment, the electric lock operation switch 4 is constituted by one pressed lead switch, and the
Compared to the conventional example in which locking operation switches were provided separately (two), the configuration of the operation display section 6 is simplified, and the information panel 2 can be further downsized.
Less wiring for operation switches (3 wires → 2 wires)
It's becoming like that. In the embodiment, the operation display section 6 is arranged on the information panel 2, but it may be arranged on another device, or the operation display section 6 may be arranged independently. good.
